Pigeons

Pigeons are flying (web)rats which live in every major city. Their job is to watch closely every bus stop (or tram stop for that matter) and report back any changes in timetables to the headquarter.

Features

• Compatibility with every major public transport company's website in Poland.
• It's live on my server. Visit http://api.bagate.la/_utils to access all the data pigeons have been gathering for some time now.

Installation

$ npm install pigeons

Testing

$ node specs.js

Usage

To get data from any source:

var Pigeons = require('pigeons'),
    config = { ... }; // See Configuration section below

new Pigeons(config, function(){
  // This function is called after logs database has been created.
  this.getAll(function(){
    // This function is called after all timetables have been
    // downloaded, parsed and saved to the database.
  });
});

There is also a couchapp which displays logs. Works only if you enable logging to couchdb. To generate couchapp type:

$ couchapp push couch/app.js http://localhost:5984/pigeons

Since it uses couchapp module, you might have to install it (npm install couchapp).

Configuration

In order to read any type of timetables from almost any source, you need to provide a few lines of configuration. That is CSS selectors of some key elements on pages we will traverse. Visit https://gist.github.com/887597 to see some examples.

CAUTION

API might change in the future.
